Does anyone have data about the most common street knife attacks?

This may have been posted elsewhere but I thought this would be the best place

I was wondering if anyone knew the most common knife attack scenarios in street situations were? I would imagine it would be torso stabs or head slashes buy I wasn't sure, plus I had a look around and couldn't find anything.

It might just be I suck at looking for this kind of thing but any links or info would be appreciated.
